i would agree in principle, but what, exactly, would be needed to be done to a gen 1 SBC to convert it over to roller lifters?

Read the last paragraph of my post. This is for a Gen I that has no provision for the OEM roller. Probably the easiest and least cost approach is to locate a pick-up with a provisioned block, many were used with flat tappet cams in them from 1986 through 1995. For 350 roller tappet blocks look for casting numbers 10243880, 14011148, 14088526, and 14093638. There is a block in this period casting number 14101148 this is a flat tappet truck block, its casting number is very similar to 14011148 which is a roller provisioned block. the 880 is the L31 Vortec block but it actually starts to show up in 95 production with a flat tappet cam and the pre L31 steel timing cover.

This has nothing to do with the tread : I ran roller cams back in the 1960s, and my father did in the 50s!! With Zddp!!! A lot of young hot rodders and enthusiasts think roller cams are a new innovation! LOL

Are you asking a question you need an answer for? Because the difference is very simple ! (I never heard of rollerized cams!) I have used rollerized cam bearings and the last ones I installed the block machining for it was $700.00! A little expensive for most people and not needed for most engines the lead Babbitt bearings work well enough !unless you want extended life for race type abused engines or industrial engines that run 24 hrs. a day 365 days a year ! When you say "roller cam' its understood by most engine builders and cam co.'s that your talking about a cam ground and designed for roller lifters! Usually an engine builder uses rollerized cam bearings after many Babbitt bearing failures! Or is running them to head them off On very expensive engines!
